Agreed, the USA was completely dominant in the past in basketball -- however, I'm not sure that I see a difference between World Champions and NBA Champions -- the NBA today is made up of basketball players all across the world -- BUT the NBA is STILL the most dominating basketball in the World. Sure, the USA Olympic teams have been beaten (of course, I would challenge the idea that we are really sending our best -- while the rest of the world certainly is) is quite true -- but we aren't talking USA -- we are talking NBA. Let's take an NBA "dream team" and pit it against any other league in the world's "dream team." Anyone want to bet against the NBA dream team?
This sounds like the Spurs trying to be "politically correct." I see the NBA as far more than the USA today -- some of the NBA's greatest stars aren't native to our country but it still makes them part of the USA.
Until other leagues can accomplish the salaries and the prestige that the NBA has, the NBA Champions is the same as the World Champions. Remember, that even the teams that have beaten the USA are dominated and led by NBA players.
